WATERMED

WATer use Efficiency in natural vegetation and agricultural areas by Remote sensing in the MEDiterranean basin
NUMBER: ICA3-CT-1999-00015
Start Date: 01/02/2000 End Date: 31/01/2003
SUMMARY: (20/09/2000)
The general objective of the WATERMED project is to develop a comprehensive method for the study of the water use and the resistance to the drought of the natural and irrigated vegetation in the Mediterranean Basin, by means of a combined historical and current space-based remote sensing database, vegetation models and field measurements. The general concept is to integrate all available data of the studied environments.
EXPECTED RESULTS:

1. Maps of critical parameters at regional and local scales, of:

    1. land surface temperature, with an accuracy of about 1.3 K,
    2. land surface emissivity, with an accuracy of about 1%,
    3. evapotranspiration, with an accuracy of +/- 1 mm/day.
    4. atmospheric total water vapour content, with an accuracy of about 0.6 g cm-2,
    5. normalized difference vegetation index (NDVI), and albedo.

2. A retrospective study of the Mediterranean Basin at the regional level, using NOAA data from 1981 to present combining data from the visible (VIS), near infrared (NIR) and thermal infrared (TIR).

3. Application of the resistance indexes, developed in semi-arid areas, to more degraded areas.

4. Evaluation of the vegetation resistance to the aridity and the severe drought periods (summer periods and the severe interannual periods) for mapping the grade of water use efficiency.

5. Evaluation of the vegetation resistance and water use efficiency in relation to the environmental factors and Land Use.
